Fervo's engineered geothermal reservoir in Utah starts feeding the grid at 33 MW
Fervo Energy is selling 33 MW from Cape Station in Utah to the grid, the first utility-scale next-generation geothermal plant to do so, Canary Media reported. The unit has only just started ramping up, so there is no long-run output record yet.
The Scientist · Science desk
Cape Station in Utah will eventually be 500 MW. Fervo says the remaining 400 MW, supported by a new Google agreement, is under construction and slated to come online in 2028. Fervo operates a 3.5 MW commercial pilot plant in Nevada, Project Red, which went online in late 2023.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Cape Station, eventual size | 500 MW | 4 | |
| Remaining, slated 2028 | 400 MW | 7 | |
| Project Red pilot, Nevada | 3.5 MW | 8 |
What happened
- Commercial operations are due to begin on Thursday, with Fervo supplying carbon-free electricity to Shell Energy, a retail power provider in California.
- Other geothermal plants use naturally occurring hot water and steam, while Fervo drills with oil and gas techniques to build reservoirs in hot, dry rock.
- Fervo is working to commission two more 33-MW blocks by 1 January 2027, and the remaining 400 MW, backed by a new Google agreement, is slated for 2028.
Why it matters
- cost Fervo told Canary Media its Phase 1 cost is $7,000 per kilowatt, about 3.2 times the 2025 gas-plant average of $2,157; Phase 2 at $5,500 is about 2.5 times.
- contradiction A $2 billion budget over 500 MW works out to $4,000 per kilowatt, below both phase figures, so either later phases are far cheaper or the figures cover different things.
- constraint Fervo declined to disclose terms for power purchase agreements covering about 1,000 MW, so what buyers pay cannot be set against its build costs.
The claim that southern Utah could not have hosted a conventional plant comes from the developer. Dawn Owens, Fervo's senior vice president and head of development and commercial markets, said: "Traditional geothermal would have never been done in southern Utah." [6] A connected, exporting block [1] supports the narrower point that oil and gas drilling techniques can build a working reservoir in dry rock at this site [5].
The thing this doesn't tell you is how the reservoir behaves once ramp-up ends. The unit was turned on late last week and has been testing and ramping up output since [2]. Output figures are not part of the report.
Scale needs a denominator. The first block is 6.6% of the planned 500 MW [14]. It is about 9.4 times the 3.5-MW Project Red pilot that Fervo has run in Nevada since late 2023 [15][8]. Owens said the pilot was important for demonstrating the technology itself [9]. Canary Media wrote that firing up Cape Station proves the approach can achieve utility scale and export power to wider markets [16]. "This is massive for both Fervo and the geothermal industry at large," Owens said [17]. Geothermal supplies 0.4 percent of total US electricity generation each year [10].
In our view, the start of operations settles whether the method can be built and connected at this site. It leaves open whether output and economics hold across 500 MW. We would want the second and third blocks on the grid, and several months of output data, before calling Cape Station a production result.
What to watch
- Whether the second and third 33-MW blocks are commissioned by Fervo's 1 January 2027 target.
- Whether Fervo publishes output data from the first block once ramp-up ends.
- Whether Fervo discloses power purchase terms or explains how the $2 billion budget squares with its per-kilowatt costs.
